DMMGAMES has announced their latest battle RPG, Koihime Taisen, which is set to launch on Android, iOS, and PC in Spring 2026 in Japan. This is the latest addition to the beloved Koihime Musō series, and is now open for pre-registration.
Get ready to build your dream team of legendary heroes
So, Koihime†Taisen is based on the classic Koihime Musō series, best known for their adult visual novels and strategy games. But, this time, it comes as a hero battle RPG, where legendary characters from the Three Kingdoms and Warring States eras are reimagined as adorable anime-like heroines.

The best part? This is the first title in the IP to bring together characters across the entire series. Now, lore-wise, you and your team is suddenly pulled to a ruined alternate world, tasked with saving the Princess from a mysterious organization. Moreover, you also need to escape this world.
Honestly, I’m excited to build my team with heroes like like Momoka, originally Liu Bei Xuande, Kuon, originally Oda Nobunaga, then upgrade their skills for tactical battles. But I think fans will love the Harem system more, as it lets you bond and increase affections with these heroes. Overall, it’s not looking bad.
Koihime Taisen is offering a variety of pre-registration milestone rewards which you’ll get at launch, which are as follows:
- 10,000 Pre-registrations: 500 Tensou stones
- 30,000 Pre-registrations: 1,000 Tensou Stones, 10 Musou Emaki Gacha Tickets
- 50,000 Pre-registrations: 1,500 Tensou Stones, 5 Koihime Gacha Tickets
- 100,000 Pre-registrations: 2,000 Tensou Stones, 10 Musou Emaki Gacha Tickets
- 150,000 Pre-registrations: 2,500 Tensou Stones, 5 Koihime Gacha Tickets
Koihime Taisen is launching on Android, iOS, and PC in Spring 2026 in Japan. You can now pre-register for the game via your respective Google Play Store, App Store, or DMM GAMES website. The App Store listing suggest a February 5, 2026 release, though it can change, so stay tuned for more updates!
